Abstract
The invention belongs to the technical field of new energies, and particularly relates to an optical linear Fresnel lens solar-energy photo-thermal conversion system. The optical linear Fresnel lens solar-energy photo-thermal conversion system is characterized by comprising a sunlight tracker, wherein a supporting plate is arranged on the upper surface of the sunlight tracker; a box-type lens supporting frame is arranged on the upper surface of the supporting plate; a Fresnel lens is arranged in the box-type lens supporting frame; and an input pipeline and an output pipeline are arranged in the sunlight tracker and connected with a high-temperature energy storage device. According to the technical scheme, optical linear Fresnel and an independent-column design are adopted, and the area of a daylighting panel can optionally range from 55-200 squares, the optical linear Fresnel lens solar-energy photo-thermal conversion system is small in occupied land, low in cost, high in conversion efficiency (can be up to 40% or above), and strong in practicability, can be implemented on such scattered lands as communities and hills, and therefore, is wide in application range.
Description
technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to an optical linear Fresnel lens solar photothermal conversion system. Background technique [0002] With the continuous growth of the global population and economic scale, the environmental problems and incentives caused by energy use are constantly being recognized, not only the hazards of smog, acid rain, etc., but also the global climate change caused by the increase in the concentration of carbon dioxide in the atmosphere. confirmed as an indisputable fact. In this context, a series of new technologies such as "carbon footprint", "low carbon economy", "low carbon technology", "low carbon development", "low carbon lifestyle", "low carbon city", "low carbon world", etc. Concepts and new policies came into being. The concept of the low-carbon era is promoting the rapid development of the solar thermal high temperature solar energy industry. The automatic adjustme...
